678970-54-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 678970-54-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,8,9,7 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 678970-54:
(8*6)+(7*7)+(6*8)+(5*9)+(4*7)+(3*0)+(2*5)+(1*4)=232
232 % 10 = 2
So 678970-54-2 is a valid CAS Registry Number.
